-
Patent number: 8410332Abstract: Medical articles including an absorbent layer, a backing layer and an optional liquid permeable facing layer are disclosed. The construction of the medical article is such that volumetric expansion of the absorbent layer is allowed in directions parallel to the surface of the backing layer as the absorbent layer absorbs moisture. The medical article may include a debonding agent located between the absorbent layer and the backing layer. The absorbent layer is operably attached to the backing layer. When the absorbent layer absorbs moisture, e.g., wound exudate, at least a portion of the absorbent layer detaches from the backing layer such that the absorbent layer can expand and move relative to the backing. The debonding agent facilitates this change from attachment to detachment of the absorbent layer to the backing.Type: GrantFiled: October 12, 2009Date of Patent: April 2, 2013Assignee: 3M Innovative Properties CompanyInventors: Scott A.

Publication number: 20120046582Abstract: A medical dressing for chest wounds, including a one-way valve that can be covered so as to protect against intrusion of airborne contaminants and to prevent passage of fluids in either direction, and including indicia visible using night vision devices but not visible in visible light to the naked eye in some embodiments. The indicia visible using night vision devices may be included in other medical apparatus, as well, so that the medical dressings or other apparatus can be used effectively during darkness, in combat situations, without being seen by enemy combatants not equipped with night vision devices.Type: ApplicationFiled: December 10, 2010Publication date: February 23, 2012Inventors: Lance David Hopman, Lane Michael Johnson, Jaret Dwayne Schaffer, Samuel Scheinberg

Publication number: 20120041353Abstract: Apparatus and associated methods for a wound valve assembly provide an annular space extending radially around a central portion of a valve, which valve acts to substantially relieve pressure build up in a thoracic cavity when applied to a thoracic wound. In an illustrative example, the valve assembly may form an annular space that extends radially in all directions around a check valve. In some examples, gasses and exudates may flow substantially radially and/or parallel to the patient's local body. Various embodiments may advantageously provide open fluid communication for the gasses and exudates escaping from the wound when the valve assembly is partially covered (e.g., body armor, clothing, blankets), or when the patient may be laying down on the side of the body with the wound, for example.Type: ApplicationFiled: August 16, 2010Publication date: February 16, 2012Inventors: William Scheremet, Steven J. Brinkman, Kim A. Jacobsen

Patent number: 8114433Abstract: A hemostatic device for promoting the clotting of blood includes a gauze substrate, a clay material disposed on the gauze substrate, and also a polyol such as glycerol or the like disposed on the gauze substrate to bind the clay material. When the device is used to treat a bleeding wound, at least a portion of the clay material comes into contact with blood emanating from the wound to cause the clotting. A bandage that can be applied to a bleeding wound to promote the clotting of blood includes a flexible substrate and a gauze substrate mounted thereon. The gauze substrate includes a clay material and a polyol. A hemostatic sponge also includes a gauze substrate and a dispersion of hemostatic material and a polyol on a first surface of the substrate.Type: GrantFiled: October 19, 2009Date of Patent: February 14, 2012Assignee: Z-Medica CorporationInventors: Raymond J. Huey, Denny Lo, Daniel J. Burns, Giacomo Basadonna, Francis X. Hursey

Patent number: 8115048Abstract: Devices, bandages, kits and methods are described that can control or regulate the mechanical environment of a wound to ameliorate scar and/or keloid formation. The mechanical environment of a wound includes stress, strain, and any combination of stress and strain. The control of a wound's mechanical environment can be active, passive, dynamic, or static. The devices are configured to be removably secured to a skin surface in proximity to the wound site and shield the wound from endogenous and/or exogenous stress.Type: GrantFiled: January 22, 2009Date of Patent: February 14, 2012Assignee: The Board of Trustees of the Leland Stanford Junior UniversityInventors: Geoffrey C. Gurtner, Reinhold H. Dauskardt, Michael T. Longaker, Paul Yock
